The Azure Content Delivery Network is designed to send audio, video, apps, photos and other files to your customers faster and more reliably, using the servers closest to each user. Acceleration Data Transfer provides dynamic site acceleration of non-cacheable, dynamic content generated by your web applications.

US government entities are eligible to purchase Azure Government services from a licensing solution provider with no upfront financial commitment or directly through a pay-as-you-go online subscription.

Important: The price in R$ is merely a reference; this is an international transaction and the final price is subject to exchange rates and the inclusion of IOF taxes. An eNF will not be issued.

Azure Germany is available to customers and partners who have already purchased this, doing business in the European Union (EU), the European Free Trade Association (EFTA) and in the United Kingdom (UK). It provides data residency in Germany with additional levels of control and data protection. You can also sign up for a free Azure trial.

Acceleration Data Transfer

Acceleration Data Transfers, also called Dynamic Site Acceleration (DSA), accelerates web content that is not cacheable, such as shopping baskets, search results and other dynamic content. While static object delivery (traditional CDN) mainly uses caching to improve website and download performance, DSA optimises routing and networking between the requester and content origin. Optimally configured, DSA can significantly improve the performance of the entire website.

The price for DSA is the same across Standard and Premium profiles (and represents the total charge).

Enterprise customers who would like to make minimum monthly traffic commitments are eligible to get discounted pricing. Please contact us to get more details.

Support and SLA

Technical support for all generally available Azure services, including Content Delivery Network, is offered through Azure Support starting at $29/month. Billing and subscription management support is provided at no cost.

We guarantee that at least 99.9% of the time Content Delivery Network will respond to client requests and deliver the requested content without error. We will review and accept data from any commercially reasonable independent measurement system that you choose to use to monitor your content. You must select a set of agents from the measurement system’s list of standard agents that are generally available and represent at least five geographically diverse locations in major worldwide metropolitan areas. For more details, see the SLA.

FAQ

Content Delivery Network data transfer pricing is based on the node location from where the transfers are served, not the end user’s location. The following geographical areas correspond to the zones for the Azure Content Delivery Network as listed above. For a detailed listing of node locations, please refer to the documentation for Point of Presence (PoP) locations.

Zone 1: North America, Europe, Middle East and Africa

Zone 2: Asia Pacific (including Japan)

Zone 3: South America

Zone 4: Australia

Zone 5: India

Your Content Delivery Network outbound data transfers are aggregated each month during your billing cycle. For Standard and Premium outbound data transfers the first 10 TB are charged at the first price point, the next 40 TB at the second, and so on. For example, if you use 50 TB of Standard data transfers in Zone 1, 10 TB will be billed at $0.081 per GB, and the next 40 TB will be billed at $0.075 per GB. For Acceleration outbound data transfers the same process is used with the first 50 TB being used for the first price point.

No. The data centre is selected based on the end users’ network configurations and cannot be controlled by the developer. Users may be served by locations that are preferred by their ISP or nodes that are “closer” in a logical sense, not necessarily in physical proximity.

When the Content Delivery Network receives a request for an object that is not at an edge location, it makes a request to Azure Storage to obtain the data. For Azure CDN from Verizon and Azure CDN from Akamai, the cost of reading data from Storage and transferring data from Storage to Content Delivery Network is based on regular Storage and Data Transfer charges. For Azure CDN from Microsoft, any data transfer from an origin hosted in Azure is included in the base Azure CDN pricing.

The availability of content in the Content Delivery Network’s local caches (often called "cache efficacy" or "offload") is influenced by multiple factors including:

Expiration (“max-age”) header values

Overall total size of the developer’s content library (how much could be cached)

Active working set (how much is currently cached)

Traffic (how much is being served)

Cache churn (how often are objects being added to cache, or ageing out)

For example, a developer with high churn and high traffic has less cache efficacy than other users because objects are swapped in and out more frequently. This incurs higher Storage and Data Transfer charges, as more origin requests are required.

To reduce the need to make origin requests, you can make longer max-age headers, allowing the Content Delivery Network to hold objects for longer.
